Abstract

Rouleau de traitement cylindrique perfectionné, destiné à être utilisé dans un dispositif de traitement photographique entraîné par un moteur, du type qui étale une composition de traitement fluide en une couche mince, sensiblement uniforme entre des couches choisies d'unités de film à auto-traitement, de type intégré, tout en faisant avancer les unités de film vers l'extérieur d'un appareil de prise de vues après leur exposition. Le rouleau selon l'invention comporte une surface périphérique nouvelle, rendue rugueuse par un procédé qui utilise un laser pulsé pour former une pluralité de cratères microscopiques dans la surface. La surface pourvue de cratères confère au rouleau une caractéristique de frottement élevé pour transporter les unités de film, tout en étant insuffisamment rugueuse pour laisser des marques quelconques, visuellement perceptibles sur elles. Application à la photographie.
